UNITED STATES PATENT OFFICE THOMAS D. GASHIN, OF MONTROSE, PENNSYLVANIA.

SEESAW.

SPECIFICATION forming part of Letters Patent No. 357.577, dated February15, 1887. Application filed August 21, 1886. Serial No. 211,468. (Nomodel.)

To all whom it may concern:

Be it known that I, THOMAS D. CASI-IIN, a citizen of the United States,residing at Montrose, in the county of Susquehanna and State ofPennsylvania, have invented certain new and useful Improvements inSeesaws; and I do herebydeclare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention consists of an improved seesaw, having the features andconstructed in the manner hereinafter described and claimed. It isillustrated in the accompanying drawings, in which Figure 1 is anelevation in perspective. Fig. 2 is a longitudinal View, in section, ofthe fulcruln-piece and the arms attached thereto; Fig. 3, a detailviewof the'fnlcrum-piece; Fig.

A, a detail of one of the arms, and Figs. 5 and 6 views, partly insection, of modifications.

In the drawings, A is a central fulcrumpiece, which is there showncircular in form, but which may be square or of other suitable form, andis provided with sockets a of an oblong shape.

B and B are the arms of the seesaw, curved from near their center totheir inner ends, and beveled at such ends. These ends of the arms areplaced in the sockets a, and one or both of them may be permanentlysecured 'to the fulcrum by means of pins d, or other fastenings, passedthrough the section 6 of the fulcrum, between the sockets a, and throughthe ends-of the arms, as shown in Fig. 2; but the arms can be attachedto the fulcrum for use by simply inserting their beveled ends in thesockets Without additional securing. The arms are curved, as shown, sothat when detached from the fulcrum they may be placed together spoonfashion, thus occupying but little space indoors when not in use, and toincrease convenience of packing into a small compass for purposes oftransportation. If desired, one of the arms may be permanently securedto the fulcrum, and the detachable arm can be then packed just as wellagainst the other. If also desired, the arms B B may be made straight.

IE E are cords for connecting and supporting the arms B B. Instead ofcords other suitable arms, rigid or flexible, may be employed.

In the modification shown in Figs. 5 and 6 the fulcrum is provided withbut a single socket, and the arms are hinged together. To one side ofthe socket a is made fast the arm B, the inner end of which is beveledand provided with the holes b b, with which hooks c c on the end of thedetachable arm B are made to engage. I

The arms B B may be provided with crosspieces at their outer ends forsupports for the riders.

Having thus described my invention, what I clairnisl. A seesaw formed oftwo curved arms, in combination with a central fulcrum, to which theinner ends of said arms are independently attached, substantially asdescribed.

2. A seesaw comprising, in combination, the central fulcrum, which restsand rocks directly on the ground or other surface upon which it rests,the separate and independent arms, and the supports connecting the arms,substantially as described.

3. In a seesaw, the combination of the curved arms beveled at theirinner ends, and a central fulcrum having sockets for the reception ofsaid arms, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

, THOMAS D. OASHIN.
